> Phoenix support hash join & sort-merge join. But in case of big*big join does not
process well.
> Therefore Need other method like Hive.
> I implemented hive-phoenix-handler that can access Apache Phoenix table on HBase using
HiveQL.
> hive-phoenix-handler is very faster than hive-hbase-handler because of applying predicate
push down.
> I am publishing source code to github for contribution and maybe will be completed by
next week.

> please, review my proposal.
